Trevor Olson announces a feature has become generally available:
Shortcuts in OneLake allow you to quickly and easily source data from external cloud providers and use it across all Fabric workloads such as Power BI reports, SQL, Spark and Kusto. However, each time these workloads read data from cross-cloud sources, the source provider (AWS, GCP) charges additional egress fees on the data. Thankfully, shortcut caching allows the data to only be sourced once and then used across all Fabric workloads without additional egress fees.
This is useful for data that hardly ever changes, and Trevor also shows you who can control the cache length and reset the cache. In addition, the on-premises gateway for shortcuts is now generally available, so you can take shortcuts of certain on-prem file systems.
